|
||||
<p>Glances is a cross-platform curses-based monitoring tool which aims to
|
||||
present a maximum of information in a minimum of space, ideally to fit
|
||||
in a classical 80x24 terminal or higher to have additional information.</p>
|
||||
<p>Glances can adapt dynamically the displayed information depending on the
|
||||
terminal size. It can also work in a client/server mode for remote monitoring.</p>
|
||||
<p>Glances is written in Python and uses the <a class="reference external" href="https://code.google.com/p/psutil/">psutil</a> library to get information from your system.</p>

||||

|

<p>Simply run:</p>

<div class="section" id="client-server-mode">

<h2><a class="toc-backref" href="#id6">Client/Server mode</a></h2>
|
||||
<p>If you want to remotely monitor a machine, called <tt class="docutils literal">server</tt>, from another one, called <tt class="docutils literal">client</tt>,
|
||||
just run on the server:</p>
|
||||
<pre class="code console literal-block">
|
||||
<span class="generic output">server$ glances -s</span>
|
||||
</pre>
|
||||
<p>and on the client:</p>
|
||||
<pre class="code console literal-block">
|
||||
<span class="generic output">client$ glances -c @server</span>
|
||||
</pre>
|
||||
<p>where <tt class="docutils literal">@server</tt> is the IP address or host name of the server.</p>
|
||||
<p>In server mode, you can set the bind address <tt class="docutils literal"><span class="pre">-B</span> ADDRESS</tt> and listening TCP port <tt class="docutils literal"><span class="pre">-p</span> PORT</tt>.</p>
|
||||
<p>In client mode, you can set the TCP port of the server <tt class="docutils literal"><span class="pre">-p</span> PORT</tt>.</p>
|
||||
<p>Default binding address is <tt class="docutils literal">0.0.0.0</tt> (Glances will listen on all the network interfaces) and TCP port is <tt class="docutils literal">61209</tt>.</p>
|
||||
<p>In client/server mode, limits are set by the server side.</p>
|
||||
<p>The version 1.6 introduces a optional password to access to the server <tt class="docutils literal"><span class="pre">-P</span> password</tt>.</p>

<h1><a class="toc-backref" href="#id10">Configuration</a></h1>
|
||||
<p>No configuration is needed to use Glances.</p>
|
||||
<p>Furthermore, starting from release 1.6, it has been introduced a configuration file for setup limits.</p>
|
||||
<p>By default, the configuration file is under:</p>
|
||||
<pre class="code console literal-block">
|
||||
<span class="generic output">/etc/glances/glances.conf (Linux)</span>
|
||||
</pre>
|
||||
<p>or:</p>
|
||||
<pre class="code console literal-block">
|
||||
<span class="generic output">/usr/local/etc/glances/glances.conf (*BSD and OS X)</span>
|
||||
</pre>
|
||||
<p>To override the default configuration, you can copy the <tt class="docutils literal">glances.conf</tt> file to
|
||||
your <tt class="docutils literal">$XDG_CONFIG_HOME</tt> directory (e.g. Linux):</p>
|
||||
<pre class="code console literal-block">
|

<span class="generic output">mkdir -p $XDG_CONFIG_HOME/glances
|
||||
cp /etc/glances/glances.conf $XDG_CONFIG_HOME/glances/</span>
|
||||
</pre>
|

<p>On OS X, you should copy the configuration file to <tt class="docutils literal">~/Library/Application Support/glances/</tt>.</p>

"In short it is the average sum of the number of processes

waiting in the run-queue plus the number currently executing
